Two novel thermotropic liquid crystalline substituted oligo(p‐phenylene‐vinylene)s: Single crystal X‐ray determination of an all‐trans oligomeric PPV

Conjugated polymers, for example PPV and polythiophene, show great potential for applications in thin‐film microelectronic and optoelectronic devices. An understanding of structure–property relationships in these materials is therefore of great importance. Here, the successful preparation of two novel substituted five‐ring oligo‐PPVs and the first crystallographic characterization of a single‐crystal all‐trans PPV oligomer are reported.
